TAPE-APPLYING FASTENEB-SETTING MACHINE.

Application filed April 9,

This invention relates to machines for setting fasteners, moreparticularly what may be termed barrel fasteners, having tubular orcylindrical portions which extend through the work and which are headedover on opposite sides, such for example as lacing hooks, beingconcerned more particularly with means by which a reinforcing tape maybe fed with the work so that the fasteners -when set fix the tape to thework. In accordance with this invention" provision is made by which whenthe desired number of fastenings have been set the length of tapethrough which they pass may be readily detached from the remainderthereof. In order that the lengthof tape may conform. to work in which aseries of fasteners are set in other than a'straight line, and withoutthe necessity of slitting the tape between successive fasteners, thisinvention contemplates the use of biastape. By using a bias tape as astay for the work the fasteners may be set simultaneously in the workand the stay, while the stay is being conformed in an uninterrupted flatlength to the fastener line by distortion of the tape in its own plane.By cutting such tape partly across at the proper intervals sectionsfixed to the work by the series of fasteners may be readily detachedfrom the remainder of p by merely pulling therefrom, Provision istherefore made in the invention .by which at the completion of thesetting of each series of fasteners the tape is slit to define atransversely weakened break line for a succeeding; length of tape to beby the setting of a succee ing series or row of fasteners, the distancebetween successive slits being adjustable to provide for differentspacing and number of fasteners in each row. v 1

Figure 8 is a fragmentary view of the shoe upper showing the tape'andhooks applied, the facing strip being partly detached. Figure9 shows inplan a pieceof bias tape showing the manner in which it is slit detachedtheretable at by means of a compression spring 7 surrounding the lifterrod 6 and bearing at its upper end against the bracket 3 and engagingthe collar 'T fixed to the rod 6 at its lower end. At 8 is indicated apunch and set holder carried by a slide 9 movable so that the punch mayform a hole in the work supported on the work table 1 when substantiallyin tne dotted line position shown in Figure 1, and then carry theworkinto the ful line positionshown' in Figure 1 in alinement with ahook-presenting and setting mechanism indicated generally at 10. Thismechanism is of any usual construction and is well known in the art sothat further detail showing is unnecessary.

At 15 (Figures 1, 2, 5 and 6) is shown a support carried by the "machineframe, this support having a "5'' slot 16 cut in its lower face as shownbest in Figures Zand 6.

\Vithin' this T slot is slidable a correspondingly shaped membcrl?carried at the up- I per end of a block 18. This block 18 cut away aboveits lower end to form a pair of posts 19 defining a guidewaytherebetween in which is slidably guided for vertical movement theportion 20 of a knife carrrier 21. On one side of this knife carrier isa thin bladed knife 22 which projects do' in;

7 fast to the face 31 OJ. me.

wardly past the corresponding face of the block 18, this knife beingfixed to the carrier as by means of a screw 23. On the other side of thecarrier 21 is fixed a clamping plate 2% "for a purpose whichwill laterapn 17 1 pear. The lower race oi the blOCK 18 is provided with aslotthrough which a tape 26 may be passed to he presented superposed onthe work to the fastener settingmechanism. A cover plate 27 fixed to thelower face of the block 18 acts to hold the tape in position in theslot. A plate 28 having a slot 29 in one face through which the knife 22may pass and a slot 30 through which the tape may be threaded is madehlecl: as by means of screws 32. The knife thus enclosed, the block andplate acting as a die and supporting the tape on hoth sides adjacent tothe cutting line. The carrier 21 is normally held in elevated positionby means of a spring iractingr bet-ween the lower face of the portion 20of the carrier and the upper face of the block 18 between the posts 19.Above the carrier 21 is pivoted on the screw a lever 11, one end ofwhich engages the upper face of the block 21 and the other end 12 ofwhich extends laterally from the block 18 in position to be contacted bythe outer end of a plate ltcarricd at the upper end of the presser tootlifter rod 6. By raising this prcsser' toot litter the lever 11 isrocked to depress the carrier'21, causing the knife 22 to be projecteddownwardly and cut a slit throughthe tape, the knife being narrower thanthe slot 25 and positioned centrally thereof so that an uncut margin, asshown at in Figure 9, is left at the ends of each slot- 51 formed by helrni'fe. When the knife 22 in -.jectcd position, having effected theslitting of tl-e ape, the plate 24. clamps the tape againrt the upperedge of the cover plate 2'? tor a purpose which will later apiear. I V

The block 18 tor theslittiuj and. clamping mechanism is adjustablealong; the support 15 and in order to hold it in adjusted posi tion alocking finger may be tired to one face thereof by means of a screw 56,this linger engaging over the upper face of the support 15 and having a.V shaped projection 57 on its low taco engageable selec-, tively in anyoi": a u'ality oi notches 58 in the upper face of tlIG/SUPPOT'L 15.

The presser toot lifter may be actuated in time with the starting andstopping of the machine. For this purpose a lever 6G pivoted at (51 tothe machine frame has one arm 62 engageable with the lower end ot thepresser toot litter rod 6. To the other end of this arm 63 is attached achain 3-1 fastened to the heel end of a foot treadle 65 (sec Figure l).7 To the toe end of this treadle is fixed a chain 66, the upper end ofwhich is attached to a controller rod 67 for the starting and stoppingmechanism. This mechanism may be of any suitable construction, buthereinhetore shown is of the well known pin type in which the upper endof the controlling rod 67 has an abutment member 68 which may he raisedinto the path of motion of a stop lug 69 of the clutch or depressed outof contact therewith. When the ahutmentfiS is out of the path of thelug, the clutch is connected for operation of the machine, but when theabutn'ient 68 is allowed to raise as soon as the clutch lug" 69 contactstherewith, its rotation stopped thereby and the clutch is disconnected.i

A tape, preferably a bias tape, is threaded through the slots 30 and 25ot the amide block 18 while the knife and clamp ca rr cr is in retractedposition and the end of the I tape is brought through a slot in a guide8 movaole with the punch carrier river the worlr trhle to an extentsutiicient to be engaged and punched when the machine is started. i

The presser foot is then rai d' e depressing the lecl of the. treadle topermit work to be inser ed thereunder, thus causing the carrier todescend and cut a slit through the tape and to lamp the tape betweenthis slit and the fa. b81161 ing mechanism. The toe of the treadle isthen depres-ised, per initting the presser foot to clamp the work inposition and pernri v.ng the s 'iring 35 to retract the knife andclamping plate from the tape. Sufficient depression oi: the toe ot thetreadle acts to start the mach ie, whereupon the punching; device ismoved from its last setti g position over the end of the tape which ispunched thereby as the punch descends to form a hole in the work. Thepunch then mores by engagement with the tape and the work, feeding bothtogether to the setting position where a hook: presented to the hole andset through hcto work and the tape. The punch then s and retracts andforms a succeeding no through both the tape and the work in which thenext hook .L. Se l:

continuing until the a osired number of hoolis in the series having beenset through both the tapeamlthe work. he tape being a bias tape permitsthe fasteijiers to he set in other than a stra. line, the tape beingcrnriornied in continuous lint condition to the configuration therioitas ted without requiring any sh t ing of the tape between the successivein Figure 8.

l/Vhen the desired number of fasteners has been set the operatordepresses the heel end of the trcadle causing the machine to stop andthe presser foot to be r: nd to reicase the work. This causes the hnheand clamping plate to be brought down, the knife acting to slit the tapeat a distance space-d,

Ill)

from the slit first cut sufiicient to define a section of tape of alength suitable for setting the desired number of fasteners in asucceeding series, the slitting and clamping mechanism being adjustablealong the sup port 15 to provide for different numbers of fasteners tobe and variations in the spacing thereof.

After the presser foot has been raised the work may be removed from themachine'and by a quick pull thereon the tape "section fixed to the workby the series of fasteners set therein may be detached from therell'litlllClfl Of the strip of tape at the slit first made by the knifewhich is now between the clamping mechanism and the setting mechanismand leaving the forward end of the succeeding length projecting throughthe guide 33 in position to be engaged and punched on a succeedingactuation of the machine, The clamping plate 2-: bearing on the tapebetween the knife and the setting mechanism prevents the break fromoccurring at the knife. This is clearly shown in Figure 9, the tapesection attached to the work V parting fronrtlie remainder of' the tapestrip at a, while being clamped at the line I) and newly slit at c.

Where bias tape-is employed not only is it possible to conform the tapeto the'configuration of the line of fasteners, but it also renders easythe detachment of a section made fast to the work at the slit, it onlybeing necessary to separate the oppositely extending short diagonalth'readsat .the narrow uncut margins as shown more clearly in Figure 9,it being unnecessary to break any threads in this operation.

A succeeding piece ofwork may then be placed beneath the presser foot inposition for the punch to punch the tape and the work and then feed thetwo to setting position to successively set thedesircd series offasteners therein whereuponon stopping the machine and raising thepresser foot as just described the next section of tape attached to thework may be detached at the adjacent slit 51, a slit defining the rearend of the succeeding section being made when the presser foot israised.
